BRUSH.

SPECIFICATION forming part of Letters Patent No. 449,344, dated March 81, 1891. i

Application filed .Tune 26,1890. Serial No. 356,850. (No model.) i

To all whom. t may concern.;

Beit known that I, MOCLINTOCK YOUNG, of Frederick, in the county of Frederick and State of Maryland, have invented certain Improvenients in Brushes, of which the following is a specification.

This invention relates to brushes,in which the folded or doubled tufts are seated in holes in a block or body and each secured by a separate fastening device seated Within the bight or fold; and it consists in a fastener composed of wire bent to a U form, and in the combination 'of said fasteners with the body and the tufts, as hereinafter explained.

In the accompanying drawings, Figure l is a transverse section of abrush in accordance with my invention on the line l l, Fig. 2. Fig. 2 is a section on the line 2 2 of Fig. l. Fig. is a face view of the block or body with fasteners therein, the tufts being omitted to expose the fasteners to view. Fig. 4 is a perspective view of one of the fasteners.

Referring to the drawings, A represents the block or body, usually a single piece of wood, having the series of tuft-receivi ng holes a bored into the same from one face and but part Way therethrough.

B B represent the tufts, each consisting of a bunch of fibers or bristles folded or doubled at the middle. Each tuft is thrust at the folded end into one of the holes, andis Wholly independent of the other tufts and their fast enings.

C C represent the fastenings seated one within the bight or fold of each tuft and deeply within the body. Each fastening consists of a short length of wire bent into substantially U form, its two arms being preferably arranged with a slight divergence toward their ends.

I commonly use stiff steel wire, and bevel the ends of the arms that they may engagev in the wood.

The fastening is driven down :firmly into the bight of the tuft and its ends separated and seated in the Walls of the tuft-hole, so that the tuft is held down securely in place.

Wire of any suitable form in cross-section may be employed; but the round wire is preferred, for the reason that it presents no corners or angles to cut or break the fiber.

It is to be particularly observed that the arms of my fastener extend outward toward the face of the brush-block-that is to say, toward the mouth of the opening through which the yfastener is inserted-so that when the arms or extremities of the fastenerare seated in the walls of the hole the fastener becomes in effect an inverted arch, acting to hold the tuft firmly in position. VAny strain tending to withdraw the tuft from the hole has the effect of causing the ends of the fastener to engage the more firmlyin the walls of the hole. The maintenance of this engagement is also insured by the stiffness or elasticity of the wire, which tends to hold the arms outward.

l. In a brush, the combination of the body having a tutt-hole therein, the folded tuft inserted in the said hole; and a U-shaped fastener inserted in the hole and within the tutt, the ends of its arms being presented toward the mouth of the hole and seated in its side walls, substantially as described, whereby the fastener is given the effect of an inverted arch.

2. As a new article of manufacture, a tuftfastener for use in brushes, consisting of a single piece of wire presenting a straight middle portion,wit.h the two ends turned upward at substantially right angles thereto, said device of a size adapted for introduction into an ordinary tutt-receiving hole.

3. The tuft-fastener consisting of the wire bent into U shape and beveled at its two ends, whereby it is adapted to firmly engage the walls of the hole in which it is inserted.

In testimony whereof I hereunto set my hand, this 21st day of June,-1S90,in the presence of two attesting witnesses.
